H A D | snoop_filter.cc | diff 12353:5650eb170bfb Mon Sep 26 11:43:00 EDT 2016 Nikos Nikoleris <nikos.nikoleris@arm.com> mem: Handle CMO responses in the snoop filter Previously responses would either transfer the ownership of the line or the actual data to the cache that send out the original request. Cache clean operations are different since they bring neither data nor ownership. When they are also invalidating the cache that send out the original request will invalidate any existing copies. This patch makes the snoop filter handle the cache clean responses accordingly.
